【问题描述】：

我有“PUT”方法的代码，请告诉我我的整个方法有问题...代码在服务器端没有影响...请告诉我，因为我比较新鲜，所以我不知道有什么问题用我的代码

     -(void)PutMethod:(NSString *)url andPostData:(NSString *)putData
     
NSLog(@"%@",url);//here get the right url which i want..
NSLog(@"%@",putData);//here get right data which i want to upload...

NSData *putNSData=[putData dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSLog(@"NSData : %@",putNSData);

NSString *putLength =[NSString stringWithFormat:@"%lu",(unsigned long)[putData length]];
NSLog(@"%@",putLength);

NSMutableURLRequest *request=[[NSMutableURLRequest alloc]init];
[request setURL:[NSURL URLWithString:url]];
[request setHTTPMethod:@"PUT"];
[request setValue:putLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:putNSData];

NSURLConnection *connection=[[NSURLConnection alloc]initWithRequest:request delegate:self];

[connection start];

if (connection)

    putNSData=[[NSMutableData alloc]init];



  

这是我的委托方法：

       -(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
    
NSDictionary *dict=[NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
NSString *Success=[dict valueForKey:@"Success"];
NSString *AccessToken=[dict valueForKey:@"AccessToken"];
NSString *UserId=[dict valueForKey:@"UserId"];

NSLog(@"ReceiveData :Success : %@ \n AccessToken : %@ \n UserId : %@",Success,AccessToken,UserId);
    

请告诉我我的代码有什么问题......

【问题讨论】：

这里的方法不影响服务器端的数据，我没有得到响应

可以打印 url 和 putData 吗？

比写答案并接受它，所以它可能会帮助别人。

请提供我的代码？？？什么意思？

接受我的代码并投票，因为它可以工作......并且在服务器端生效......

【参考方案1】：

此代码完美运行。为 PUT 执行此操作：

- (void)PutMethod:(NSString *)url andPostData:(NSString *)putData 
    NSLog(@"%@", url);
    NSLog(@"%@", putData);

    NSData *putNSData = [putData dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
    NSLog(@"NSData : %@",putNSData);

    NSString *putLength = [NSString stringWithFormat:@"%lu", (unsigned long)[putData length]];
    NSLog(@"%@", putLength);

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
    [request setURL:[NSURL URLWithString:url]];
    [request setHTTPMethod:@"PUT"];
    [request setValue:putLength forHTTPHeaderField:@"Content-Length"];
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    [request setHTTPBody:putNSData];

    NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

    [connection start];

    if (connection) 
        putNSData = [[NSMutableData alloc] init];
